GovTechGuy writes: The FCC's agenda for Thursday include a vote on the final rules for unlicensed devices making use of unused TV spectrum known as "white spaces." Industry and lawmakers have predicted the opening up of the white spaces could result in the biggest leaps forward in wireless technology in the past 25 years. Among the benefits is so-called "WiFi on Steroids" which allows a large number of users within a 50-mile radius to tap into a single high-speed broadband connection for the same price as a traditional WiFi router. The FCC is expected to approve the move, but Google and other companies warn that the devil is in the technical details of the rules.
